This invention relates to a novel furnace and/Or boiler accessory such as may berconveniently referred. to as a dust and soot collector or depository.

Needless to say, I amsufiiciently conversant with the prior state of the art to realize that soot traps and equivalent devices `have been 'constructed for use in association with smoke stack conduits and piping in general. In other words, I appreciate that it is broadly old to provide accessible means whereby soot can be brushed from Y the stack pipe into a collector or receptacle and thereafter disposed of. d

It follows, therefore, that the present invention constitutes what is believed to be an irnprovement on known prior art and marketed de- It is characterized by simplicity, practicability, efficiency inoperationV and is structurally distinct, by way of contrast with known structures, in that it includes unusual `telescopic receptacle equipped means to take care of the dislodged soot.

nreducing the inventive idea to practice I have devised a substantially dust-proof structure wherein the receptacle portion thereof rests directly on the floor to relieve the stack of the hanging weight of theattachment.

Other features and advantages willV become more readily apparent fromthe following description andY drawing. Y

In the drawing:-

Figure 1 is an elevational view-showing the complete'assembly including a part of the stack, a furnace, and the improved soot collector interposed between thestack and the discharge nipple on the back of the furnace.

Figure Zfis an enlarged central .vertical VView on the line 2--2 of Figure V1.

Figure 3 is a horizontal section on the line 3-3 of'Figure 2.

In the drawing, in Figure 4 the numeral 4 designates any suitable. type of a furnace, boiler, or the like. On the back is the customary attaching nipple or neck 5. to accommodate the smoke stack pipe or conduit 6. In accordance with the present invention a T-shaped adapter union or coupling is interposed between the features 5 and 6. The main part of the coupling is indicated at 'I and the depending part 8 is` turned down to accommodate a delivery tube or pipe 9. This is fitted telescopically around the stem 8 and fas- Y tened in place. I have found it expedient and practicable to use a substantially' U-shaped fixture I for this purpose. This is in effect a saddle and is placed over the ,T-coupling and the free ends of the arms thereof terminate in hooks I I engaged with eyes l2 o n the ends of aconnecting and hanger link or rod I3 carried by theupper end portion of the soot and dirt delivery pipe or tube 9. The lower end `of the part 9 vfits Vtelej pipe 9.

scopically into an elongated receptacle or cup I4 and the two features 9 and I4 are thus extensible to permit the collector to be interposed between the floor I and the T-coupling or other connecting means on the lstack 6. That is to say, these features cooperate to render the device selff adapting whereby the charged cup or receptacle I4 may rest directly on'the floor to relieve the stack 6.0i a hanging weight such asis some-l times found to be evident in prior art devicesI.

It will be noted that the T-coupling is as close Y aspossible to the furnace. This puts it in Va po sition to enable a brush or reach implement (not Y Y shown) to be placed in the top of the furnace to literally dust the soot into the receptacle I4 by way of the delivery pipe or connection 9.

Novelty is predicated'upon the idea of resting the cup I4 directly on the floor I5 and affording adjustable communicating connection between it and the stack E. Then too, the specific T-coupling and connecting pipe 9 cooperating withthe cup I4 is believed to be an ingenious adaptation in this particular line of endeavor. Additional novelty appears to reside in the saddle-like retainerV lll having hooked releasable connection `with the eyes I2 on the ends of the connecting link I3, thus affording a novel separable. Vconnection between the T-coupling l andthe delivery It is thought that the description taken in connection with the drawing will enable a clear understanding of the invention to be had. Therefore, a more lengthy description is thought unnecessary.

While the preferred embodiment of the invention has been shown and described, vit is to be understood that minor changes Vcomingwithin the field of invention claimed may be resorted to ifA desired.

What is claimed is:-

1. AA soot collector of the Class described comprising a T-coupling, a delivery pipe attached to theV short branch or stem of said coupling, a cylindrical cup consttuting'a receptacle, said pipe having one end fitting telescopically into said receptacle, a saddle bridging the T-coupling, a pin carried by the adjacent end portion of said pipe, said pin terminating in eyes, said saddle having its end portions terminating in hooks releasably engageable with said eyes.

2. The combination with the smoke pipe of aV WILLIAM NULLE.
